"The Champion for Hogwarts is... Cedric Diggory!"
"Woooohhh!!" *clap* *clap*
foosh*
"Harry Potter??"
"Ahh same old as always. Can't I just take a break just once and seep my precious tea here in silent?"
"Annoying Carnivore I'll bite you to death"
"Ahhh Kyo-chan you're still cute as always"
"Shut up Tiny Carnivore"
"Who is he Harry? Why does he looks like you?"
"Well... he's my grandson"
"WHAT?!"
"A H-hibari?! You married a Hibari?! One of the strongest clans in Asia that they're known for being the 'Dragons in the East! That Hibari!?! "
"Hey don't diss my wife's clan or I'll make sure to break every bones your body have and you won't move for even a year. I didn't get my title 'Storm of the Eye' for nothing"
"WHAT?!"
"Harry! I'm still too young to be called grandpa!"
"More like great-great grandpa"
"Shut it!"
"Harry can you tell us about your wife?"
"That's the loveliest thing I've ever heard! Xiu Ying was the most beautiful and deadliest person I've ever known! Did you know that our first meeting when introducing ourselves was we're fight to death? Oh she was so lovely even in her bloody dress..."
"What happen to those two?"
"Listening to the lovesick fool about his wife"
"Aahh"
A/N: As you can see, still not good at making a chapter for a story. And sorry for the wrong grammars when you read it.
The gist in this story is that after the war in Hogwarts, Harry became an Unspeakable in the Time Chambers Department. In there he accidentally use a malfunctioned Time Turner where he arrived at the 1940's and was deaged. Due to the Potter Luck strikes again (let just say that the Potters were cursed with 'May you lived in interesting times') he was kidnapped and shipped to China. There he escapes from the human traffickers and meet his mentor who will teach him about the culture of China and be the mentor in the martial arts. And the rest was history in meeting his wife, Xiu Ying, and having children and became an Arcobaleno.
In the Future-That-Will-Never-Happened, as Yuni sacrificed herself for reviving the Arcobalenos and the past receiving the memories from the future that's where the Potter Luck strikes again. Fon didn't revived but his soul and memories were transferred to his past!HogwartsHarry when he was in his 4th year during the selecting of the Champions by the Goblet of Fire.
When Kyoya returned to the past and meet his grandfather Fon in his babified form he knew right away that he didn't received the memories from the future but instead from his past. There he came in his glory by destroying and crashing the doors in Hogwarts and demanded a fight from his past grandfather and that's where chaos reign in because of his looks who looks the same with Harry.
Just comment if you perhaps want to adopt this idea and make it a better one.
